Influenza viruses, particularly avian strains, continue to evolve rapidly, yet the antiviral properties of Jordan\u2019s native plants remain largely unexplored. This study focused on avian influenza and screened twelve endemic plant species, using ethanol to selectively extract polar phytochemicals likely to interact with the hydrophilic active site of neuraminidase (NA). Among these, Arbutus andrachne leaf and fruit extracts emerged as potent in vitro inhibitors of recombinant N9 neuraminidase, a key enzyme in influenza replication, with IC50 values of 31.6 \u00b5g\/mL and 32.9 \u00b5g\/mL, respectively. LC-MS analysis identified hyperoside as the major shared flavonoid in both extracts, which may contribute to the observed inhibitory activity. These findings support the potential of A. andrachne as a natural source for herbal preparations with antiviral activity.<\/jats:p>","DOI":"10.3390\/life16040560","type":"journal-article","created":{"date-parts":[[2026,3,30]],"date-time":"2026-03-30T13:41:03Z","timestamp":1774878063000},"page":"560","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Arbutus andrachne Extracts Exhibit In Vitro Neuraminidase (N9) Inhibitory Activity: A Potential Herbal Strategy Against Avian Influenza"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4978-5059","authenticated-orcid":false,"given":"Areej","family":"Abuhammad","sequence":"first","affiliation":[{"name":"Department of Pharmaceutical Sciences, School of Pharmacy, The University of Jordan, Amman 11942, Jordan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fatma","family":"Afifi","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Sciences, School of Pharmacy, The University of Jordan, Amman 11942, Jordan"},{"name":"Department of Pharmaceutical Chemistry and Pharmacognosy, Faculty of Pharmacy, Applied Science Private University, Amman 11931, Jordan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9586-4722","authenticated-orcid":false,"given":"Nour H.","family":"Aboalhaija","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Sciences, Faculty of Pharmacy, Al-Zaytoonah University of Jordan, Amman 11733, Jordan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammed H.","family":"Kailani","sequence":"additional","affiliation":[{"name":"Department of Chemistry, School of Science, The University of Jordan, Amman 11942, Jordan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4453-072X","authenticated-orcid":false,"given":"Mutasem O.","family":"Taha","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Sciences, School of Pharmacy, The University of Jordan, Amman 11942, Jordan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tamara","family":"Sabri","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Sciences, School of Pharmacy, The University of Jordan, Amman 11942, Jordan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zahra","family":"Fauri","sequence":"additional","affiliation":[{"name":"Department of Chemistry, School of Science, The University of Jordan, Amman 11942, Jordan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ismail","family":"Abaza","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Sciences, School of Pharmacy, The University of Jordan, Amman 11942, Jordan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,3,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Roychoudhury, S., Das, A., Sengupta, P., Dutta, S., Roychoudhury, S., Choudhury, A.P., Ahmed, A.B.F., Bhattacharjee, S., and Slama, P.
